Robust 57-tooth spur for small-scale ARRMA vehicles

Made from 40Cr carbon steel, this 0.5 module 57-tooth spur is a heavy duty replacement for small-scale electric trucks and buggies. The 0.5Mod profile works with common small-scale pinions and helps restore correct mesh, tweak gearing, or replace a worn factory component (it can replace a 59T spur in some ARRMA configurations).

During installation, set spur-to-pinion mesh to recommended clearance, keep backlash within usual RC practice, and make sure the gear seats flush on the gearbox shaft. After fitting, rotate the drivetrain manually and re-check mesh before running to confirm smooth operation.

  • Spur Gear 0.5 module 57 tooth - 1pcs

Is this spur a straight swap for ARRMA small-scale gearboxes?

In many cases yes, but confirm shaft seating and mesh before final assembly. The 0.5Mod tooth form matches standard 0.5Mod pinions used on the listed ARRMA small-scale models.

Will the 57T reduce load on the motor compared with 59T?

A 57T spur changes the final ratio slightly versus a 59T, which can affect torque and top speed. Check driveline behaviour after swapping to ensure the motor and ESC operate within safe limits.

How do I check backlash correctly?

Set a small amount of play between spur and pinion, rotate the drivetrain and feel for any binding, then tighten mounting hardware and re-check rotation. Aim for smooth, free movement without excessive lash.
